Dentists' skills with fearful patients: education and treatment

Changes in symptoms of anxiety, depression, and PTSD in an RCT-study of dentist-administered treatment of dental anxiety

BACKGROUND

Educating dentists in treatment methods for dental anxiety would increase the patients' access to treatments that are important to their oral health. However, to avoid adverse effects on comorbid symptoms, involvement by a psychologist has been considered necessary. The objective of the present paper was to evaluate whether a dentist could implement systematized treatments for dental anxiety without an increase in comorbid symptoms of anxiety, depression or PTSD.

METHODS

A two-arm parallel randomised controlled trial was set in a general dental practice. Eighty-two patients with self-reported dental anxiety either completed treatment with dentist-administered cognitive behavioural therapy (D-CBT, n = 36), or received dental treatment while sedated with midazolam combined with the systemized communication technique "The Four Habits Model" (Four Habits/midazolam, n = 41). Dental anxiety and comorbid symptoms were measured pre-treatment (n = 96), post-treatment (n = 77) and one-year after treatment (n = 52).

RESULTS

An Intention-To-Treat analysis indicated reduced dental anxiety scores by the Modified Dental Anxiety Scale (median MDAS: 5.0 (-1,16)). The median scores on the Hospital Index of Anxiety and Depression (HADS-A/D) and the PTSD checklist for DSM-IV (PCL) were reduced as follows: HADS-A: 1 (-11, 11)/HADS-D: 0 (-7, 10)/PCL: 1 (-17,37). No between-group differences were found.

CONCLUSIONS

The study findings support that a general dental practitioner may treat dental anxiety with Four Habits/Midazolam or D-CBT without causing adverse effects on symptoms of anxiety, depression or PTSD. Establishing a best practice for treatment of patients with dental anxiety in general dental practice should be a shared ambition for clinicians, researchers, and educators.

TRIAL REGISTRATION

The trial was approved by REC (Norwegian regional committee for medical and health research ethics) with ID number 2017/97 in March 2017, and it is registered in clinicaltrials.gov 26/09/2017 with identifier: NCT03293342.

Clinical and medico-legal considerations in endodontics

Endodontic treatment can be challenging for a number of reasons, including the microscopic nature of the clinical environment, reliance on tactile sensation and lack of direct visualization of the work being performed. Commonly, endodontic patients present with pain and distress, which can exacerbate an already difficult clinical situation. Complications may might arise prior to, or during treatment, despite practising with the utmost care and skill. Preventing and managing these complications can take considerable time and energy, and oftentimes assistance from or referral to more experienced colleagues is required. The aim of this review is to discuss medico-legal considerations in endodontics, with clinical correlations and a focus on the Australian legal landscape.

Relationship between Children's and Parents' Dental Anxiety: A Cross-Sectional Study on the Six European Countries

Background: The purpose of this study is to investigate the relationship between children’s and parents’ dental anxiety. Methods: 731 children of different ages and their parents from six European countries participated in this study. Dental anxiety was investigated through an online questionnaire, which consisted of general questions and the Corah Dental Anxiety Scale (CDAS), which is a questionnaire that measures respondents’ reactions on a 5-point scale for four different situations. Results: CDAS results were calculated for all children and their parents. A total of 12.5% of children from Croatia, 26.67% from Macedonia, 10.94% from Bosnia and Herzegovina, 20.31% from Montenegro, 23.08% from Slovenia and 16.10% from Serbia showed a high level of anxiety. The correlation between dental anxiety of parents and children was 0.4 (p < 0.01). Conclusions: Parents with negative experience from a dental office can have a bad effect on their child’s behaviour, which results in the creation of a non-active patient. Due to the clear and existing cause-and-effect relationship of dental anxiety in children and parents, it is extremely important to educate parents about the proper psychological approach to children in order to promote positive experiences from dental offices, as well as to emphasize the importance of regular visits to the dentist.

Dental students' and patients' perceived importance and knowledge of dental anxiety

AIM

To examine the perceived importance and knowledge of the dental students' in their treatment of dental anxiety according to their year of study and to find out patients' perceived importance of the dental students' knowledge of dental anxiety according to their level on dental fear.

METHODS

Dental students (N = 219) at the University of Turku and non-probability convenience sample of 100 of patients attending the Dental Teaching Clinic were given questionnaires with multiple choice and open-ended questions. Students were categorised into three groups according to the year of study (1-3, 4, 5). Patients were categorised into three groups using the established cut points for Modified Dental Anxiety Scale (no fear = 5-9, low fear = 10-18, high fear = 19-25). The differences between groups were evaluated using cross-tabulations, chi squared and Fisher's exact tests. The open-ended questions were subjected to content analysis.

RESULTS

Students' perceived importance of dental anxiety did not differ between three groups. Students with greater undergraduate education and clinical experience were more likely to have excellent or quite good knowledge (P < .001). Patients' perceived importance of dental students' knowledge of dental anxiety was greater in patients with high level of fear. The overlapping category that emerged from the open-ended question analysis was communication skills. This appeared to be important for patients with dental anxiety and for dental students in their management of dental anxiety.

CONCLUSION

Clinical communication skills should be part of dental anxiety management teaching. Dental students should be able to gain sufficient knowledge and skills in treating dental anxiety before graduating.

Smelling Anxiety Chemosignals Impairs Clinical Performance of Dental Students

Despite the fact that human body odors can transfer anxiety-related signals, the impact of such signals in real-life situations is scant. In this study, the effects of anxiety chemosignals on the performance of dental students operating on simulation units, wearing T-shirts imbued with human sweat and masked with eugenol were tested. A total of 24 fourth-year dental students (17 F) donated their body odors in two sessions (Anxiety and Rest). Twenty-four normosmic, sex- and age-matched test subjects who were third-year dental students performed 3 dental procedures while smelling masked anxiety body odors, masked rest body odors, or masker alone. The intensity and pleasantness ratings showed that the test subjects could not report perceptual differences between the odor conditions. When exposed to masked anxiety body odors, the test subjects' dental performance was significantly worse than when they were exposed to masked rest body odors and masker alone, indicating that their performance was modulated by exposure to the emotional tone of the odor. These findings call for a careful evaluation of the anxiety-inducing effects of body odors in performance-related tasks and provide the first ecological evaluation of human anxiety chemosignal communication.

Development and evaluation of the Jönköping Dental Fear Coping Model: a health professional perspective

OBJECTIVE

The purpose of this study was to design a structured treatment model focusing on all levels of adult's dental fear, the Jönköping Dental Fear Coping Model (DFCM). The aim was to study the DFCM from a dental health professional perspective.

MATERIAL AND METHODS

The DFCM was studied by means of quantitative and qualitative analyses. Nine dental clinics participated in Period I (pre-intervention/standard care), and 133 dental health professionals (dentists, dental hygienists, dental assistants) and 3088 patients were included. After completion of Period I, four of the clinics were randomized to Period II (intervention), beginning with the professionals undergoing DFCM training. Following that, 51 dental health professionals treated 1417 patients according to the DFCM. The other five clinics served as controls.

RESULTS

Half or more of the dental health professionals assessed the model as better than standard care, regarding anamnesis and diagnostics, communication and contact, and understanding of patients and dental fear. The dental health professionals reported higher tension in their fearful patients in Period II compared with Period I, possibly due to their increased awareness of dental fear.

CONCLUSIONS

The qualitative data suggest that dental health professionals find the DFCM beneficial in routine dental care. The model promotes a holistic approach to the treatment of adult patients. However, stress among the professionals was not reduced when measured, neither quantitatively nor qualitatively. It is important to evaluate the model in further studies to make it possible to draw generalizable conclusions.

Validation of Universal Scale in Oral Surgery (USOS) for Patient's Psycho-emotional Status Rating

Objectives

There aren’t any objective methods that may help in standard evaluation of oral surgery patient’s psycho-emotional status. Without any standardized evaluation, two main problems appear: heterogeneity between studies and ineffective patient’s evaluation. Therefore, Universal Scale in Oral Surgery (USOS) for patient’s psycho-emotional status rating has previously been proposed by authors. The aim of present study is to assess the clinical effectivity and validate the Universal Scale in Oral Surgery in case of outpatient tooth extraction for adult healthy patients.

Material and Methods

Clinical trial to validate the USOS for patient’s psycho-emotional status rating was performed. In total 90 patients, that came for outpatient dental extraction to Lithuanian University of Health Sciences Oral and Maxillofacial Surgery Department ambulatory, were enrolled in clinical trial. Patients filled self-reported questionnaires before the procedure. Operating surgeon rated USOS for patient’s psycho-emotional status rating doctor’s part questionnaire after the procedure. 4 - 6 weeks later all patients were asked to fill USOS for patient’s psycho-emotional status rating questionnaire retrospectively.

Results

According to the statistical analysis, the final composition of USOS for patient’s psycho-emotional status rating that would fit to reliability coefficient should be composed from 6 patient part questions and 3 general doctor part questions.

Conclusions

Universal Scale in Oral Surgery for patient’s psycho-emotional status rating is a novel, doctor and patient rated scale which is suitable for clinical and scientific usage.

Dental students' attitudes towards management of pain and anxiety during a dental emergency: educational issues

INTRODUCTION

High levels of patients' pain and anxiety characterise dental emergencies. The main objective of this study was to examine the self-reported attitudes of dental students towards these parameters in emergency conditions. A secondary objective was to determine if individual parameters (gender, personal experience of dental pain, personal dental anxiety and year of study) might affect their attitudes.

METHODS

One-hundred and eighty-seven undergraduate dental students with clinical practice completed a multiple-choice self-administered questionnaire online. The aforesaid individual parameters were collected and the students were asked to rate the frequency of their behaviour towards items representing good management of patients' pain and anxiety. The chi-square test of independence, Fisher's exact test and multiple logistic regression models were used for statistical analysis.

RESULTS

Oral assessment of anxiety before treatment was scarce and was significantly associated with the students having personally experienced dental pain (P = 0.007). Pre-, intra- and postoperative pain appeared to be managed unequally by the students. Male students were significantly less likely to inform patients about postoperative pain (P = 0.014). More clinical experience was associated with less systematic consideration for intra-operative pain (P < 0.05). Being dentally anxious showed no significant association with higher frequencies of behaviours towards patients' pain and anxiety.

CONCLUSIONS

These findings highlight the need for educational improvement regarding pain and anxiety in emergency conditions, especially concerning the assessment methods and continuity in the control of pain. Emergency dental care appears to be a very suitable field for contextual learning.

Scales used to rate adult patients' psycho-emotional status in tooth extraction procedures: a systematic review

The aim of this study was to review scales used to assess anxiety, stress, and pain in dental patients undergoing a tooth extraction procedure and to propose a novel psycho-emotional rating scale based on the relevant literature and our own experience. An electronic literature search was conducted of the National Library of Medicine database MEDLINE (Ovid) and EMBASE databases between January 2005 and April 2016. Sequential screening at the title/abstract and full-text levels was performed. The review included all human prospective or retrospective follow-up studies and clinical trials, cohort studies, case-control studies, and case series that demonstrated at least one scale used to measure tooth extraction anxiety, stress, or pain. The search resulted in 32 articles meeting the inclusion criteria. None of the studies were found to be suitable in evaluating patient's stress, pain, and fear at once. Also, no scales were found that included both the doctor's and the patient's rating. In a few studies, vital signs as psycho-emotional status indicators were rated. Guidelines for a suitable questionnaire that could be used for rating the psycho-emotional status of patients undergoing tooth extraction are listed in the present research. Further studies are required for verification and validation of offered scale.

Oral Hygiene in Patients With Severe Mental Illness: A Pilot Study on the Collaboration Between Oral Hygienists and Mental Health Nurses

PURPOSE

To test (a) the effects of an educational intervention about oral hygiene on the knowledge of mental health nurses, and (b) the effects of an oral care intervention on oral health in patients with severe mental illness (SMI).

DESIGN AND METHODS

We applied a pretest/posttest design to test improvements in nurses' knowledge and the oral health of SMI patients.

FINDINGS

The nursing staff's knowledge increased significantly after the educational intervention. The oral health of the patients improved significantly after the oral health intervention.

PRACTICE IMPLICATIONS

Oral health of SMI patients can improve significantly with basic oral health interventions carried out by collaborating oral hygienists and mental health nurses.

Dentists' use of behavioural management techniques and their attitudes towards treating paediatric patients with dental anxiety

PURPOSE

The purpose of this study was to explore the relationship between dentists' education in treatment of dental anxiety (DA), dentists' attitudes towards patients with DA and dentists' use of BMT.

METHODS

An anonymous questionnaire was sent electronically to 611 dentists in the Public Dental Service in Norway. Statistical evaluation was done using cross tabulation with Chi square and logistic regression analyses.

RESULTS

The response rate was 65 % (n = 391). About half of the respondents (53 %, n = 208) had followed postgraduate courses in treating patients with DA. The following were the most common attitudes towards treating young patients with DA: it feels like making a contribution (72 %, n = 286), it is difficult or tiresome (54 %, n = 215) and it is a positive challenge (51 %, n = 203). Dentists who had taken postgraduate courses in DA more often reported anxious patients as a positive challenge (60 vs. 42 %, p < 0.001) and were less reluctant to treat these patients (5 vs. 15 %, p = 0.002). The most frequently used BMT was tell-show-do (87 %, n = 340), followed by relaxation (35 %, n = 132), distraction (25 %, n = 94), systematic cognitive behaviour therapy (22 %, n = 84) and conscious sedation (18 %, n = 69). Dentists without postgraduate courses in DA used fewer techniques when treating these patients (OR 2.1, 95 % CI 1.3-3.3, p = 0.001) compared with dentists who had taken these courses.

CONCLUSION

Country of graduation and postgraduate courses in DA had a strong relationship with dentists' use of BMT and dentists' attitudes towards young patients with DA.

Experiences of dental care and dental anxiety in adults with autism spectrum disorder

Dental anxiety is associated with previous distressing dental experiences, such as lack of understanding of the dentist intentions, perceptions of uncontrollability and experiences of pain during dental treatment. People with autism spectrum disorder (ASD) are impaired in building flexible predictions and expectations, which is very much needed during a dental visit. The aims of the study were to investigate if people with ASD have more negative dental experiences and a higher level of dental anxiety compared to a matched control group. Forty-seven adults with ASD and of normal intellectual performance, and 69 age- and sex-matched typically developing controls completed questionnaires on previous dental experiences and dental anxiety, the Dental Anxiety Scale, and the Dental Beliefs Survey. The ASD group experienced pain during dental treatments more often than the controls and 22% had repeatedly experienced being forced to dental treatment they were not prepared for, compared to 3% of the controls. A higher level of dental anxiety was reported by the ASD group. Dental treatment and methods for supporting the communication with patients with ASD need to be developed, in order to reduce the negative dental experiences and dental anxiety in people with ASD.
